Summary
Williamson County does not run water utilities. Outdoor watering limits come from your retail provider, such as Georgetown, Round Rock, Brushy Creek MUD, Jonah Water, or Chisholm Trail SUD, whose drought contingency plans set stage watering schedules under state law.
The commission shall by rule require wholesale and retail public water suppliers and irrigation districts to develop drought contingency plans consistent with the appropriate approved regional water plan to be implemented during periods of water shortages and drought.
Full Breakdown
Texas Water Code Section 11.1272 requires wholesale and retail water suppliers to adopt drought contingency plans, and TCEQ mandates them for systems with 3,300 or more connections. Williamson County's water flows from the Brazos River Authority, the Lower Colorado River Authority, and local groundwater, delivered by municipal utilities and special districts. Each provider's plan defines drought stages that cap landscape irrigation, often two days per week at Stage 1 and one day at Stage 2, tightening as reservoir and lake levels fall. The schedule that binds a specific address is set by that address's retail provider, not by the county.
Violations & Fines
Watering outside your provider's assigned stage schedule draws warnings, escalating fines, and possible flow restriction under the utility's drought plan. Penalty amounts are set by each provider, not the county.
